This video shows our very first test with PIC microcontrollers. This was an easy one, just flashing some LEDs alternatively. In this test we used a PIC12F675 running @4MHz using its internal clock. You can see a 7805 voltage regulator and an electrolitic capacitor, used together as a little stabilized power supply for the PIC. Also, a 1Kohm resistor was used as pull-up for the MCLR pin.

Please help me with this picture problems! Emtec Movie Cube P800 is used for recording my analogue signal over chinch cable which gets it's picture over a wireless 2,4GHz receiver. Problem as you can see: every second you get a ugly color distorsion. Tried the following: another wireless receiver (from fatshark video goggles) - same problem. the same video transmitter works fine when using my old USB capture device - so I see no problem in the wireless transmission of the image! Setting various resolutions in the P800 changes no thing. If I connect a videosource directly only by cable (Sony Camcorder with Chinch-Out) there is no such distortion. I did't try the lower quality recording modes yet - but I don't think they will change a thing... A slight chance may be an firmware upgrade... (fw upgrade was not possible today- another story) another FPV cam (with 420TVLines resolution instead of 480) = same problem! FINDOUT 1: when cam is in BW mode - the distortions are gone: www.youtube.com Please comment if you have a tip! Background: FPV Recorder I bought a new mpg2 recorder which seems quite a good solution for FPV video recording: 2 USB Hostports (you can connect USB Stick or HDD for recording onto it. Even an SD Cardslot for recording on SD Card! Power consumption is OK: about 350mah for 20mins of recording (it uses 5v) that would make 1000mah for one hour. A cheap 2cell lipo with voltage regulator will be fine here. Recording CONTINUES after a bad signal (or even if ...

Diy bench power supply (not finish) you can see the increase in power when I turn the switch, this is due to a change on the negative that goes into the voltage regulator LM350 form the -12V to the 0v or ground from the ATX inside. I'll post more videos and the link to the page where i explain how to make this bench power supply as soon as i finish.

Seconds impulse slave clocks with alternating polarity and current driven. These clocks were designed for series connection in a current controlled driver circuit with alternating polarity every second. Drive current may be between 150 and 220 mA. I got two of these clocks kindly given to me by Electromark1, and posted over from the UK to New Zealand to add to my electric master slave clock collection. The clocks were used by the BBC as silent clocks in the studio's and now replaced with newer electronic versions. I designed an simple opto coupler driven circuit which takes pulses of the Gents 1 seconds master clock. The beauty of opto pulses is that there is no burden on the pendulum, as I have lifted the 1 seconds mechanical contacts, this improves clock accuracy as well. An aluminium vane was attached to the pendulum and scanned by two opto heads as can be seen in one of my other video's. I will draw up an exact schema with the LED's in it as well and add a link in the next couple of weeks. Any questions please post here on YouTube and I will do my best to help to resolve any building issues with the electronic components. The parts are easily available from any electronics store, the optocouplers may be a bit harder to get. I got mine from some old ferraris disc utility kWh meters which were discarded at our local powerboard.

Quick and unplanned demo! :) Recapped power supply of 101 and 104, and some VCO caps of 101, replaced both voltage regulator ICs of 104, completely calibrated 101 and then hooked it all up for a spin. Much happiness ensued. Apologies for the crappy sound recording. Must make proper work of this for a next video :)

Digital thermometer using the PIC18f4520 micro controller and a DS1631 digital thermometer chip. This is all connected to an LCD screen to update the temperature of the room once a second. The connection between the chip and micro controller is I2C. I put my finger on top of the digital thermometer chip, to increase the temperature. I was using a voltage regulator to power my LCD ( from 5 to 3.3) and this is why the LCD back light flickers.

a system in which an alternator has had its regulator and diode pack removed and a new diode setup is in place, im running into a multi tap transformer giving a push pull resonance and output of 200volts (frequency aprox 216 hrtz) and at 1800rmp and only 5 volts going in .. perfect for a wind generator or higher powered hho cell (maybe) .. grin .. stanley would be impressed .. now we can see resonance in the bifilar coil(transformer) doing the push pull and the alternator as the amplitude and frequency modulators.. yes the diodes get hot but the transformer stays cool thankyou

This is a video camera I designed about ten years ago. Though not tiny by today's standards, about the size of a dice, for a short time it ruled as the smallest commercially available color video camera. Developed completely during my spare time in my small lab at home I designed the circuit board using OrCad Capture and Layout, the body using AutoCad, and would hand solder the tiny components with a regular soldering pencil. Twenty of the components (resistors, capacitors, etc.) on the printed circuit board were in 0402 packages (40 thousandths of an inch long by 20 thousandths of an inch wide). The goal was to get the circuit board down to the same size as the imaging chip which was the smallest available at the time, making it the limiting size factor for the camera. After assembly the whole camera was dipped into rubber tool grip paint to create a thin protective body. I opted to use 1/8th stereo headphone jacks as a power/video connector since regular RCA video jacks and coaxial power connectors would have nearly tripled the size of the entire package. On the circuit board you will see one standard size transistor package (TO-92). This is actually a 5 volt voltage regulator chip which allows the camera to be run safely on a power supply from about 6-14 volts. This camera became the predecessor for many others I have designed for specialized extreme pressure, extreme temperature, extreme vibration and other application projects.FlirGuy I try to respond to all requests ...

This is a how to DIY video that will teach you to make a 5 volt flashlight Mod for the Joye 510 electronic cigarette. The mod I teach you how to make I call the "Detonator" iut is a consistant 5 volts. Every time you vape the 2 cr123a batteries give you exactly 5 volt because of the inline voltage regulator. Other e-cigarette mods deliver 6 volt or more then slowly drop off as you use the PV, every hit the batteries become weaker and weaker slowly giving a lesser satisfying hit during use. The Detonator operates consistantly at 5 volt for the entire life of the rechargable protected cr123a batteries. This Detonator in the video has a red LED lit when the power is On and a blinking green LED when the attomizer is being powered. I take you through the process of making a 5 volt Detonator step by step, so that you can make your own. For those that don't want to make there own I will make one for you- just contact me for details.

This is a classic clean Tele sound through a 1960 Tweed Bassman and a 1964 Super Reverb. I have recently connected all of my vintage amps through Carl Hartman's Tone/Amp Preserver. The Preserver is a simple compact voltage regulator for anyone that would like to drop the line voltage from the current 120+ volts to the voltage of the 50's and 60's bewteen 110 and 115 volts. Your vintage amps will operate in the range they were design for and it really enhances your tone. Listen. I have it set on -6 v or 115 volts.
